Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2005/078906
Kind Code:
A1
Abstract:
A rotating electric machine the assemblability of which is improved and which includes a temperature sensor having an improved accuracy of measurement of the temperature of the stator winding wire. The rotating electric machine comprises a stator winding wire (27) provided to a stator (15), a temperature sensor (21) for estimating temperature of the stator winding wire (27), and heat-conductive brackets (2, 3) provided between the stator winding wire (27) and the temperature sensor (21). The estimate of the temperature of the stator winding wire (27) is calculated by adding the temperature measured by the temperature sensor (21) and a correction value for correcting the measured temperature.
